Cevap

An access control vestibule
An access control vestibule consists of a small space with two interlocking doors. When an authorized person passes through the first door, it must close completely before the second door unlocks and opens. This physical barrier ensures that only one person can enter per authentication event, directly stopping tailgaters.

Adım Adım Çözüm

1
Identify the physical security threat described in the scenario.
The issue is tailgating (or piggybacking), where an unauthorized individual closely follows an authorized person through a secure doorway.
Selecting the correct physical security measure requires identifying the specific access control vulnerability.
2
Evaluate the available security mechanisms to determine which one restricts entryway throughput to one authenticated person at a time.
An access control vestibule creates an enclosed double-door checkpoint that isolates individuals during access attempts.
The interlocking mechanism ensures the outer door shuts completely before allowing entry through the inner door, neutralizing tailgating attempts.
